Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, torque wrench, inspection mirror, stethoscope (optional)
Ensure the vehicle is parked on a level surface and the engine is turned off and cool.
Disconnect the battery to prevent any electrical issues.

2. Inspect Engine Mounts

1. Use a socket set to remove the bolts securing the engine mount (check left and right).
2. Visually inspect the mounts for cracks or excessive wear.
3. Replace any damaged engine mounts with OEM or high-quality aftermarket parts.
4. Torque the new mounts to the manufacturer's specifications.

3. Check Loose Components

Sub-steps:
1. Perform a visual inspection of the engine bay for any loose bolts or nuts.
2. Tighten any loose heat shields, exhaust components, or engine covers using the socket set.
3. If necessary, replace missing fasteners with OEM parts.

4. Inspect Serpentine Belt and Pulleys

Sub-steps:
1. Remove the serpentine belt by releasing tension from the tensioner pulley using a socket wrench.
